og.image.representative
The og:image represents this page and survives the unfurl crop
Why it matters
The preview image is the whole payload of a shared link. A generic site-wide banner, or artwork whose subject sits outside the ~1.91:1 crop, is present enough to pass every mechanical check and still communicate nothing.
What goflag asks you
Printed under “Needs judgment” with --advisories, alongside the observed facts the answer turns on. goflag never fills in the verdict.
Does the og:image represent what this page is about, rather than being a site-wide default, and does its subject survive being cropped to the 1.91:1 aspect ratio consumers render?
How to fix it
This rule ships no snippet, because the remedy is a judgement rather than a line of code: the finding tells you what is out of range, and what to put there is yours to decide.
Says who?
This rule is guideline, and it cites the documentsbelow. Nothing here is goflag’s opinion of what a good page looks like — if you disagree with a finding, this is what you are disagreeing with.
